ROPE-MAKING MACHINE.

Specification of Letters Patent. Patented J 1113 23, 1918 Application filed December 2, 1916. SeriaI No. 134,626.

To all whom it may concern:

Be it known that I, ROBERT Dawns, a

citizen of the United States, residing at- Philadelphia, Pennsylvania, have invented certain Improvements in Rope-Making Machines, of which the following is a specification. 2 I

My invention relates to that type of rope making machines in which are employed a series of spindles, each rotating about its own axis, the series also rotating about an axis common to all, each spindle carrying a plurality of bobbins supplying yarns which, by reason of the rotation of said spindles, are twisted into strands, said strands, by reason of the rotation of the bobbin carrying spindles about the common axis, being twisted together to form the rope.

The object of my invention is to simplify and cheapen the construction of the machine, an object which I attain by dispensing with the laying heads usually interposed between the upper sets of bobbins and the top frame or spider on the central shaft.

In the accompanying drawing Figure 1 is a view, partly in side elevation and partly in vertical section, of sufficient of a rope making machine, of the type to which my invention relates, to illustrate said invention;

Fig. 2 is an enlarged vertical section of part of the same, and

Fig. 3 is a horizontal section on the line 33, Fig. 2.

In the drawing, 1 represents a central rotating vertical shaft mounted at top and bottom in suitable bearings on the fixed frame 2 and carrying upper and lower spiders 4 and 5, which, in turn, carry a series of vertical spindles 6 (three, in the present instance), each of said spindles being rotated from the central shaft 1, by means of gearing disposed below the lower spider 5. Each of the spindles 6 has mounted thereupon, so as to rotate therewith, a series of superposed bobbin carriers 7 (three, in the present instance) and each of these bobbin carriers has mounted in it so as to be free to rotate a series of bobbins 8, (three, in the present instance), these bobbins having wound thereon the yarns which are to form the strands of the rope.

A yarn from each bobbin passes through a suitable guide on the spindle 6 and thence through a. sleeve 9 which is secured to the upperend of said spindle 6, is adapted to a bearing in its respective arm of the upper spider 4 and has a flange 10 above said bearing. Mounted upon said flange are the legs of a yoke 11 which carries a perforated block 12, the bore of which is coincident with the axis of the spindle 6 with which it cooperates, hence in passing from the sleeve 10 to the block 12, the yarns from the various bobbins carried by thespindle 6 are twisted into a strand.

These strands are directed from the blocks 12 to a sleeve 13 secured to the upper end of the central shaft 1 and turning in the upper bearing therefor, said sleeve carrying a yoke 14 with central block 15 having a bore coincident with the axis of the shaft 1, whereby the strands will be twisted 1nto a rope.

By directing the yarns from each of the bobbins carried by a spindle 6 to a sleeve mounted upon the upper end of said spindle and rotating in a bearing in the upper spider, so as to constitute the upper bearing for the spindle, I am enabled to dispense with the laying heads interposed, as in the machine shown in the Tobey Patent 868,726, dated October 22d, 1907, between the top spider and the uppermost bobbin carriers, and also with the intermediate spider employed in said machine, and therefore to that extent simplify and lessen thecost of the machine and at the same time reducethe height of the same so that it can be set up and operated in a room having only a normal height of ceiling.

The sleeves also constitute enlarged journals. for the upper ends of the spindles 6 and insure steady bearings for the same in the top spider. I

As the strands are under heavy tension their pressure upon the collecting tubes frequently causes the latter to heat, and by locating said tubes above theupper spider I prevent the heating of the spindle bearings in said spider, which occurs when the strands pass through those portions of the spindles which are contained in said bearings.

I claim 1. The combination, ina rope making ma-,

of bobbins, means for rotating each of said spindles about its axis, sleeves secured to and rotating with said spindles and each adapted to a bearing in the top spider, each of said sleeves having therethrough openings for the passage of the yarns from the bobbins carried by its respective spindle, and tubular blocks each located above the upper spider and each having a bore coincident with the axis of said spindle, in which block the yarns from the bobbins carried by said sleeve .meet and are twisted together.

2. The combination, in a rope making machine, of a central rotating shaft, top and bottom spiders thereon, spindles carried thereby and each provided with a plurality Copies of this patent may be obtained for of bobbins, means for rotating each of said spindles about its axis, sleeves secured to and rotating with said spindles and each adapted to a bearing in the top spider, each of said sleeves having therethrough openings for the passage of the yarns from the bobbins carried by its respective spindle, a flange at the upper end of each sleeve, and yokes mounted upon said flanges and each carrying a tubular collecting block having a bore coincident with the axis of its respec tive spindle, said yokes being located above the upper spider.

In testimony whereof I have signed my name to this specification. 7
